<< Outline of vehicle lighting unit >>
First, the application and schematic configuration of the vehicle lighting unit (hereinafter, vehicle lighting unit 1) according to the present embodiment will be described. The vehicle lighting unit 1 is mainly used as lighting in an internal space of a vehicle (that is, a vehicle interior) and emits light from a light emitting region provided in the vehicle interior. Specifically, in a vehicle equipped with the vehicle lighting unit 1, a door lining R as a decorative component is installed inside the door. As shown in FIG. 1, the door lining R is provided with a substantially trapezoidal recess in a side view in which a handle lever (so-called in-handle H) for opening and closing the door is accommodated. Then, the light emitting region 100 exists in the portion surrounding the depression. In addition, below, the light emitting region 100 installed around the recess in which the in-handle H is housed is referred to as a first light emitting unit 10.

  Further, as shown in FIG. 1, an elongated portion X having a substantially knife shape in a side view is provided above the recess of the door lining R in which the in-handle H is accommodated. Then, the light emitting region 100 exists at the upper end portion of the elongated portion X. In addition, below, the light emitting region 100 installed at the upper end portion of the long portion X is referred to as a second light emitting portion 11.

  By the way, in this embodiment, in the door lining R, the range from the portion where the first light emitting portion 10 is arranged to the portion where the second light emitting portion 11 is arranged is integrated as an ornament member. However, the present invention is not limited to this, and the portion in which the first light emitting unit 10 is arranged and the portion in which the second light emitting unit 11 is arranged may be configured by separate parts.

  Each of the 1st light emission part 10 and the 2nd light emission part 11 functions as a vehicle interior illumination, and lights up when the vehicle interior becomes dark, such as at night. At least one of the first light emitting unit 10 and the second light emitting unit 11 (the second light emitting unit 11 in the present embodiment) is located behind the vehicle when the door is opened while the vehicle is stopped. When an object (hereinafter referred to as an approaching object) approaches a vehicle, the object emits light to notify the occupant of the presence of the approaching object. As described above, in the present embodiment, the light emitting area 100 functions as a lighting and also functions as a notification means for notifying the presence / absence of a situation outside the vehicle (specifically, an approaching object). The approaching objects include other vehicles, people, bicycles, motorcycles, animals, and the like.

  In addition, there is a non-light emitting region that does not emit light around each of the first light emitting unit 10 and the second light emitting unit 11. More specifically, the first light emitting unit 10 is arranged around the recess that accommodates the in-handle H, and the non-light emitting region (hereinafter, the first non-light emitting region 20) is located at the front position and the rear position thereof. Is provided. Further, in the substantially knife-shaped elongated portion X provided on the door lining R, the second light emitting portion 11 is arranged at the upper end portion of the elongated portion X, and the non-luminous area ( Hereinafter, the second non-light emitting area 21) is provided.

  The first light emitting unit 10 is adjacent to the first non-light emitting region 20. Further, the appearance of the exposed surface (the surface facing the vehicle interior) of the first light emitting unit 10 is such that when the first light emitting unit 10 does not emit light, the exposed surface of the first non-light emitting region 20 (the surface facing the vehicle interior). ) Is similar to that. That is, as shown in FIG. 2A, the decoration style of the exposed surface of the first light emitting unit 10 is a style corresponding to the decoration style of the exposed surface of the first non-light emitting region 20 when the first light emitting unit 10 is not emitting light. Has become. Specifically, when the first light emitting unit 10 is not emitting light, the decorative style of the exposed surface of the first light emitting unit 10 and the decorative style of the exposed surface of the first non-light emitting region 20 are both metallic appearance. Present.

  The second light emitting unit 11 is adjacent to the second non-light emitting area 21. Also, the appearance of the exposed surface (the surface facing the vehicle interior) of the second light emitting portion 11 is such that when the second light emitting portion 11 does not emit light, the exposed surface of the second non-light emitting area 21 (the surface facing the vehicle interior). ) Is similar to that. That is, as shown in FIG. 2A, the decoration style of the exposed surface of the second light emitting unit 11 is a style according to the decoration style of the exposed surface of the second non-light emitting region 21 when the second light emitting unit 11 is not emitting light. Has become. Specifically, when the second light emitting section 11 is not emitting light, the decorative style of the exposed surface of the second light emitting section 11 and the decorative style of the exposed surface of the second non-light emitting area 21 are both metallic appearance. Present.

  As described above, since the decoration style of the exposed surface of the light emitting area 100 corresponds to the decoration style of the non-light emitting area adjacent to the exposed surface, the light emitting area 100 and the non-light emitting area are in harmony. As a result, the light emitting region 100 becomes inconspicuous while the light emitting region 100 is not emitting light (when light is not emitted), and the design of the door lining R is improved. That is, in the present embodiment, in a situation where illumination such as night is required, the light emitting region 100 is caused to emit light as shown in FIG. On the other hand, in a situation where illumination such as daytime is unnecessary, the presence of the light emitting region 100 is hidden by emphasizing the design of the door lining R as shown in FIG. 2A. Such a property is called stealth property, and in the vehicle lighting unit 1 according to the present embodiment, the stealth property is greatly improved as compared with the conventional vehicle lighting device.

  In the present embodiment, the "decorative style" means visual characteristics such as coloration, pattern, luster, and texture of the surface that appear due to the decorative treatment applied to the surface. Further, the "style according to the decoration style of the non-light emitting area" includes a style similar to the decoration style of the exposed surface of the non-light emitting area, and a style similar to the decoration style of the exposed surface of the non-light emitting area (specifically, In general, the features have a common style). Further, in the present embodiment, the exposed surfaces of both the light emitting region 100 and the non-light emitting region are metallic tones, but the present invention is not limited to this, and may be, for example, wood grain or carbon tones. Other than that, the color and pattern may be similar.

  Further, in the present embodiment, as described above, when the approaching object is approaching the vehicle from the rear of the vehicle, the second light emitting unit 11 emits light to notify the occupant of the presence of the approaching object. At this time, a portion (light emitting portion 11a) that actually emits light on the exposed surface of the second light emitting portion 11 is a part of the second light emitting portion 11 as shown in FIG. 2B. Further, the light emitting portion 11a of the second light emitting unit 11 regularly changes and moves regularly along a direction corresponding to the moving direction of the approaching object (strictly, the front-back direction of the vehicle). More specifically, the exposed surface of the second light emitting unit 11 extends in the front-rear direction of the vehicle. When there is an approaching object from the rear of the vehicle when the door is opened, the light emitting portion 11a moves at a constant speed from the rear to the front in the extending direction of the second light emitting unit 11 (that is, the vehicle front-rear direction). . Immediately after the light emitting portion 11a reaches the front end portion of the second light emitting portion 11, the light emitting portion 11a instantaneously returns to the rear end portion of the second light emitting portion 11 and then moves from the rear toward the front again.

  As described above, in the present embodiment, when there is an approaching object from the rear when the door is opened, the light emitting portion 11a of the second light emitting unit 11 moves from the rear to the front. Thereby, the occupant of the vehicle can intuitively understand that the approaching object is approaching the opened door by visually observing the movement (flow) of the light emitting portion 11a.

  In the present embodiment, the “direction corresponding to the moving direction of the approaching object” includes the direction along the moving direction of the approaching object, and further, the direction slightly inclined with respect to the moving direction of the approaching object or the movement of the approaching object. It includes a direction that is slightly curved with respect to the direction. Further, in the present embodiment, when there is an object (approaching object) approaching from the rear of the vehicle when the door is opened when the vehicle is stopped, the light emitting portion 11a is moved in the second light emitting unit 11. It is not limited to this. For example, when the lane change is performed while the vehicle (target vehicle) is traveling forward, the vehicle (rear vehicle) traveling behind the target vehicle in the lane to which the change is made becomes the target vehicle. When approaching, the light emitting portion 11a may be moved for the purpose of informing that fact. Further, when there is an object that is separated from the target vehicle, the light emitting portion 11a may be moved for the purpose of informing that fact.

<< Composition of light emitting area >>
Next, the configuration of the light emitting region 100 will be described. The first light emitting unit 10 and the second light emitting unit 11 as the light emitting region 100 are provided in each of the door lining R installed on the left side and the door lining R installed on the right side of the vehicle interior. Further, the structure of the light emitting region 100 is common between the left and right door linings R. Therefore, in the following, the light emitting region 100 provided in one door lining R (for example, the right door lining R) will be described as an example.

  Each of the 1st light emission part 10 and the 2nd light emission part 11 has the main-body part 110 and the irradiation body 120, as shown in FIG. The illuminator 120 irradiates light toward the interior of the vehicle, and includes a light source (specifically, a first light source 12 and second light sources 13a, 13b, 13c, 13d, and 13e described later) as constituent elements. Have. The illuminator 120 may further include a light guide member (light guide plate or optical fiber) for transmitting the light emitted from the light source as a constituent element.

  The main body portion 110 defines the outer shape of the light emitting region 100 and exposes the light emitting region 100 to the interior of the vehicle so as to exhibit the decorating property. More specifically, the main body portion 110 included in the first light emitting unit 10 has a substantially trapezoidal frame shape. Further, the main body portion 110 included in the second light emitting portion 11 has a linear shape extending in the vehicle front-rear direction.

  Further, the main body portion 110 has a laminated structure as shown in FIG. 3, and is composed of a base material 111 and a decorative film 112. The base material 111 corresponds to a transmissive body, is arranged at a front position of the irradiation body 120 (specifically, a position inside the irradiation body 120 in the vehicle width direction), and transmits light emitted from the irradiation body 120. Let The base material 111 is molded with a translucent resin material, specifically, ABS resin (acrylonitrile, butadiene, styrene copolymer synthetic resin), PC resin (polycarbonate resin) or PMMA resin (polymethylmethacrylate resin). It was done.

  It should be noted that the base material 111 of the main body portion 110 forming the first light emitting unit 10 contains a known light diffusing material (light diffusing material). Therefore, the light from the irradiation body 120 is diffused by the diffuser material when passing through the inside of the base material 111. As a result, when the irradiation body 120 of the first light emitting unit 10 emits light, the entire main body portion 110 including the base material 111 emits light, in other words, the entire first light emitting unit 10 emits light.

  The decorating film 112 corresponds to a decorating body, and is attached to the surface of the base material 111 (the surface located inside in the vehicle width direction). That is, the decorative film 112 is arranged at the front position of the base material 111 (specifically, the position inside the base material 111 in the vehicle width direction). The decorative film 112 is located on the innermost side (inside in the vehicle width direction) of the main body 110, and gives the main body 110 decorativeness. That is, the decorative film 112 forms the exposed surface of the light emitting region 100 exposed in the interior space of the vehicle interior.

  The decorative film 112 will be described in detail. The decorative film 112 according to the present embodiment has a multilayer structure as shown in FIG. 3, and has a pattern layer 112a and a base 112b. The base 112b is a portion made of polymethylmethacrylate resin (PMMA) or polyethylene terephthalate (PET), and is composed of a film at a previous stage where printing or the like is performed (that is, a film that is colorless and transparent and has translucency). ing.

  The pattern layer 112a is located on the exposed side in the vehicle interior of the decorative film 112, and is a metallicly colored portion in this embodiment. Specifically, the surface of the pattern layer 112a is decorated (pattern) so as to have the same decoration style as the non-light emitting area adjacent thereto. As a result, the surface of the main body portion 110 (in other words, the exposed surface of the light emitting area 100) exhibits a metallic texture like the non-light emitting area adjacent thereto. The pattern layer 112a is formed by a printing process such as gravure printing or silk screen printing. As the ink or pigment used in this process, a translucent one is used. Therefore, the light transmitted through the base material 111 can pass through the decorative film 112 including the pattern layer 112a.

  In addition, in the present embodiment, the decorative film 112 is attached to the surface of the base material 111 with an adhesive or the like. That is, an adhesive layer 112c is formed between the base material 111 and the decorative film 112 as shown in FIG. However, the method of making the surface of the main body portion 110 metallic is not limited to the method of attaching the decorative film 112, and for example, vapor deposition treatment or mirror ink coating may be performed on the resin surface of the base material 111. A method of applying is also available.

  By the way, as a method for easily associating the decoration style of the light emitting area 100 with the decoration style of the non-light emitting area (specifically, a method of unifying the decoration styles), a decoration common to the light emitting area 100 and the non-light emitting area is used. It is conceivable to use the film 112 and form the exposed surface of both the light emitting region and the non-light emitting region by the decorative film 112. At this time, it is preferable that a black ink is solidly printed by a printing process such as gravure printing or silk screen printing on the back surface of the portion of the decorative film 112 located in the non-light emitting area to form the blocking layer. . The portion provided with the blocking layer does not have a light-transmitting property and blocks the light transmitted through the base material 111. Then, by providing a difference in translucency in the decorative film 112 depending on the presence or absence of the blocking layer, only a portion of the decorative film 112 located in the light emitting region 100 has a light transmissive property while a non-light emitting region is provided. A light shielding property is imparted to the positioned portion.

<< Control mechanism in vehicle lighting unit >>
Next, the control mechanism in the vehicle lighting unit 1 will be described. As shown in FIG. 4, the vehicle lighting unit 1 includes a control device 2, a sensor, a buzzer 4, a first light emitting unit 10 and a second light emitting unit 11, and a control circuit.

  The control device 2 corresponds to a control unit, and is configured by a vehicle ECU (Electric Control Unit). The control device 2 controls the irradiation body 120 included in each of the first light emitting unit 10 and the second light emitting unit 11, and strictly speaking, the light source forming the irradiation unit 120. More specifically, when the control device 2 causes the first light emitting unit 10 to emit light, the control device 2 turns on the first light source 12 constituting the irradiation body 120 of the first light emitting unit 10 via the first light emitting unit control circuit 5A. . As a result, the entire exposed surface of the first light emitting unit 10 emits light.

  In addition, the control device 2 turns on the second light sources 13a, 13b, 13c, 13d, and 13e that configure the irradiation body 120 of the second light emitting unit 11 when causing the second light emitting unit 11 to emit light. A plurality of the second light sources 13a, 13b, 13c, 13d, 13e are provided, and the second light sources 13a, 13b, 13c, 13d, 13e are arranged in a row along the extending direction of the second light emitting unit 11 (the front-back direction of the vehicle). Then, the control device 2 selects one of the plurality of second light sources 13a, 13b, 13c, 13d, 13e, and turns on the selected one light source through the second light emitting unit control circuit 5B. As a result, as shown in FIG. 5, one portion on the exposed surface of the second light emitting portion 11 emits light as the light emitting portion 11a.

  To describe in more detail with respect to the control of the second light emitting unit 11, the control device 2 controls each of the first and second light emitting portions 11a so that the light emitting portions 11a regularly move on the exposed surface of the second light emitting unit 11 while the second light emitting unit 11 emits light. The two light sources 13a, 13b, 13c, 13d, 13e are controlled. More specifically, the control device 2 turns on one of the second light sources 13a, 13b, 13c, 13d, 13e, and the second light sources 13a, 13b, 13c, 13d, 13e to be turned on are sequentially switched. The second light sources 13a, 13b, 13c, 13d and 13e are controlled. As a result, the light emitting portion 11a moves along the front-rear direction. At this time, the light emitting portion 11a moves from the rear to the front, reaches the front end of the second light emitting unit 11, and then returns to the rear end to repeat the above movement (movement from the rear to the front).

  Regarding the moving direction of the above-described light emitting portion 11a, the order of the ones of the second light sources 13a, 13b, 13c, 13d, and 13e that constitute the irradiation body 120 of the second light emitting unit 11 to be turned on can be reversed. It can be switched. That is, the control device 2 controls the second light sources 13a, 13b, 13c, 13d, 13e so that the light emitting portion 11a moves in the direction opposite to the moving direction shown in FIG. 5 (direction from the front to the rear). It is also possible.

  The sensor corresponds to a detection unit, and when the door is opened when the vehicle is stopped (when the vehicle is in the stopped state), the sensor is used as a trigger to detect an approaching object approaching from behind the vehicle V. . Then, when the sensor detects an approaching object from the rear of the vehicle, the sensor outputs a signal corresponding to the detection result to the control device 2. When the control device 2 receives the output signal from the sensor, based on the signal, the position of the approaching object with respect to the vehicle V, the moving direction (approaching direction) of the approaching object, the distance between the vehicle V and the approaching object, and Specify the approach speed of the approaching object.

  In this embodiment, a plurality of sensors are attached to the vehicle body of the vehicle V as shown in FIG. Note that, in FIG. 6, the arrangement position of the sensor is schematically shown by a black circle. As a supplementary explanation of the sensors, as shown in FIG. 6, a total of four sensors are provided at each of the front, rear, left and right sides of the vehicle body. That is, the right front sensor 3a, the right rear sensor 3b, the left front sensor 3c, and the left rear sensor 3d are attached to the vehicle body of the vehicle V.

  In the present embodiment, each sensor is composed of a known ultrasonic sensor. However, the present invention is not limited to this, and a sensor including a microwave radar may be used together. By the way, in the case of using a sensor composed of a microwave radar, it is preferable to install the sensor inside the rear bumper of the vehicle V (for example, a portion indicated by a cross mark in FIG. 6).

  In addition, in the present embodiment, as shown in FIG. 6, two front sensors (that is, the right front sensor 3a and the left front sensor 3c) and two rear sensors (that is, the right rear sensor 3b and the left rear sensor 3d) are used. ) Are symmetrically arranged in the width direction of the vehicle V (left-right direction). However, the present invention is not limited to this, and the number and arrangement position of the sensors may be at least one in the front, rear, left, and right. For example, additional sensors may be installed at locations indicated by white circles in FIG. You may.

  The buzzer 4 is a device that generates a warning sound inside the vehicle. Although the vehicle lighting unit 1 according to the present embodiment has the buzzer 4, it may not have the buzzer 4.

  Supplementing the function of the control device 2 according to the present embodiment, the control device 2 detects the position (relative position) of the approaching object with respect to the target vehicle (hereinafter, vehicle V) when the approaching object is detected by the sensor when the vehicle is stopped. Also, the moving direction (approaching direction) of the approaching object is specified. Further, the control device 2 specifies the distance between the vehicle V and the approaching object and the approaching speed when the approaching object approaches the vehicle V based on the detection result of the sensor. Here, the “approach speed” means the relative speed of the approaching object with respect to the speed of the vehicle V. The control device 2 according to the present embodiment specifies both the distance between the vehicle V and the approaching object and the approaching speed when the approaching object approaches the vehicle V. Of these, only one of the items may be specified.

  Then, the control device 2 sets the light emission color and the moving speed of the light emitting portion 11a in the second light emitting unit 11 based on the identification results of the above two items. Then, the control device 2 controls the second light sources 13a, 13b, 13c, 13d, 13e so that the light emitting portion 11a emits light with the set emission color and moves at the set movement speed. .

  More specifically, when the control device 2 recognizes that an approaching object is approaching the vehicle V through signal reception from the sensor, the control device 2 detects the distance between the vehicle V and the approaching object and the approaching object. Identify the speed. Then, the control device 2 controls the second light sources 13a, 13b, 13c, 13d, 13e so that the light emitting portion 11a moves at the moving speed according to the above-mentioned specific result. More specifically, the control device 2 controls the second light source 13a so that the light emitting portion 11a moves faster as the distance between the vehicle V and the approaching object becomes shorter, while the light emitting portion 11a moves slowly as the distance becomes longer. It controls 13b, 13c, 13d and 13e. Further, the control device 2 controls the second light sources 13a, 13b, 13c, 13d, 13e such that the light emitting portion 11a moves faster as the approaching speed increases, while the light emitting portion 11a moves slower as the approaching speed decreases. .

  Further, the control device 2 controls the second light sources 13a, 13b, so that the emission color of the light emitting portion 11a changes to a color according to the specific result of the distance between the vehicle V and the approaching object and the approaching speed of the approaching object. Controls 13c, 13d and 13e. That is, in the present embodiment, the emission color of the light emitting portion 11a of the second light emitting unit 11 is variable. Then, the control device 2 controls the second light sources 13a, 13b, 13c, 13d, and 13e so that the light emission color of the light emission portion 11a becomes a color according to the identification result of the above two items.

  More specifically, the control device 2 determines whether or not the result of specifying the distance between the vehicle V and the approaching object exceeds a reference value (a value referred to when determining the approaching degree of the approaching object). To do. When the distance is less than the reference value, the control device 2 controls the second light sources 13a, 13b, 13c, 13d, 13e so that the light emission color of the light emission location 11a becomes the first light emission color (for example, blue). . On the other hand, when the distance exceeds the reference value, the control device 2 controls the second light sources 13a, 13b, 13c, 13d, 13e so that the emission color of the emission point 11a becomes the second emission color (for example, red). . Further, the control device 2 sets the emission color of the light emitting portion 11a to be the first emission color when the approaching speed is lower than the reference value, and controls the light emitting portion 11a when the approaching speed exceeds the reference value. The second light sources 13a, 13b, 13c, 13d, and 13e are controlled so that the emission color becomes the second emission color.

  Here, as the second light sources 13a, 13b, 13c, 13d, 13e, known ones (for example, lamps having LEDs of a plurality of colors) can be used as light sources whose emission colors can be switched. The description of the mechanism and the mechanism for switching the emission color will be omitted.

  Explaining further functions of the control device 2 according to the present embodiment, the control device 2 can control the second light sources 13a, 13b, 13c, 13d, 13e so that the light emitting portion 11a moves while blinking. Is. At this time, the control device 2 moves the light emitting portion 11a while blinking at a blinking speed according to the identification result of at least one of the distance between the vehicle V and the approaching object and the approaching speed of the approaching object. Thus, the second light sources 13a, 13b, 13c, 13d, 13e are controlled.

<< About light emission control flow >>
Next, a light emission control flow by the control device 2 will be described. When the occupant turns on a predetermined illumination lighting switch (not shown), the control device 2 causes each of the illuminators 120 (strictly speaking, the first light source 12 and the first light source 12 and the second light emitting unit 11) to turn on. The two light sources 13a, 13b, 13c, 13d, 13e) are controlled to cause each light emitting unit to emit light. Further, the vehicle V is stopped while each light emitting unit emits light, and when the passenger opens the door in such a state, the control device 2 starts the alerting control flow illustrated in FIG. 7. Hereinafter, the control flow for alerting will be described with reference to FIG. 7.

  When the control flow for alerting is started, the control device 2 determines whether or not there is an approaching object from behind the vehicle V based on the presence or absence of the output signal from the sensor (S001). More specifically, the control device 2 identifies the door opened when the vehicle is stopped. After that, when one of the right rear sensor 3b and the left rear sensor 3d located on the same side as the identified door detects an approaching object, the sensor outputs a signal to the control device 2. Upon receiving such a signal, the control device 2 determines that there is an approaching object approaching toward the opened door.

  When the control device 2 determines that an approaching object exists in step S001, the process proceeds to step S002, and when the control device 2 determines that no approaching object exists, the process proceeds to step S007.

  In step S002, the control device 2 determines the position of the approaching object (relative position with respect to the vehicle V), the distance between the vehicle V and the approaching object, and the moving speed of the approaching object (approaching speed) based on the output signal from the sensor. ), And specify. After that, the control device 2 selects the second light emitting unit 11 provided in the door lining R corresponding to the position of the approaching object specified in step S002, of the left and right door linings R (S003). The second light sources 13a, 13b, 13c, 13d, and 13e of the second light emitting unit 11 selected in this step S003 are control targets in the subsequent control.

  In addition, the control device 2 sets the moving speed and the emission color of the light emitting portion 11a in the second light emitting unit 11 according to the identification result in step S002 (S004). More specifically, the control device 2 calculates the moving speed of the light emitting portion 11a using the distance between the vehicle V and the approaching object and the approaching speed of the approaching object as parameters. At this time, the moving speed of the light emitting portion 11a is calculated to increase as the distance becomes shorter or the approaching speed becomes larger, and becomes smaller as the distance becomes longer or the approaching speed becomes smaller. Further, the control device 2 compares the distance between the vehicle V and the approaching object and the approaching speed of the approaching object with the respective reference values, and when the values are below the reference values, the emission color is changed to the first light emission. The color is set, and when the value exceeds the reference value, the emission color is set to the second emission color.

  Then, after setting the moving speed and the luminescent color of the light emitting portion 11a, the control device 2 is a control target so that the light emitting portion 11a moves along a direction corresponding to the moving direction (approaching direction) of the approaching object. The second light sources 13a, 13b, 13c, 13d, 13e are controlled (S005). More specifically, the second light source 13a is configured to move from the rear to the front at the moving speed set in step S004 while the light emitting portion 11a emits light in the light emission color set in step S004. , 13b, 13c, 13d, 13e are controlled.

  In step S005, the second light sources 13a, 13b, 13c, 13d, 13e may be controlled so that the light emitting portion 11a moves while blinking. At this time, if the second light sources 13a, 13b, 13c, 13d, and 13e are controlled so that the light emitting portion 11a moves while blinking at a blinking speed according to the distance between the vehicle V and the approaching object, the vehicle V It becomes easier for the occupant to grasp the status of the approaching object (specifically, the degree of approach).

  Further, the control device 2 reproduces a warning sound through the buzzer 4 while the second light emitting unit 11 emits light in the above-described light emission mode (S006). Here, the warning sound is a sound for making the occupant of the vehicle V notice that the light emitting portion 11a of the second light emitting unit 11 is moving.

  After that, the control device 2 repeats the series of steps S001 to S006 described above until the control end operation is performed (S007). Here, the control ending operation is an operation performed by an occupant as an operation for ending the attention control flow, and specifically, an operation of closing the door in the open state is applicable.

  Then, at the time when the control device 2 recognizes that the control end operation is performed and the operation is accepted, the control device 2 stops the movement of the light emitting portion 11a in the second light emitting unit 11 and turns on the buzzer 4. The warning sound is controlled to stop (S008). When step S008 ends, the control flow for alerting ends at that point. When the control end operation is performed before the approaching object is detected (that is, No in step S001 and Yes in step S007), the control flow for alerting ends without performing step 008. .

  As described above, in the alerting control flow, when the sensor detects an approaching object approaching the vehicle V from the rear of the vehicle V when the passenger of the vehicle V opens the door when the vehicle is stopped, it is the same as the opened door. The light emission pattern of the second light emitting unit 11 located on the side (in other words, the second light emitting unit 11 arranged on the same side as the approaching object when viewed from the vehicle V) is changed. More specifically, in the second light emitting unit 11, the light emitting portion 11a moves from the rear to the front. As a result, the occupant of the vehicle V visually recognizes the movement (flow) of the light emitting portion 11a, thereby recognizing the presence of an approaching object behind the opened door and the approaching direction.

  It should be noted that by moving the light emitting portion 11a from the rear to the front on the exposed surface of the second light emitting unit 11, the occupant intuitively understands that there is an approaching object from the rear. In the control flow for alerting, the light emission mode of the second light emitting unit 11 (specifically, movement of the light emitting location 11a) is determined according to the distance between the vehicle V and the approaching object and the identification result of the approaching speed of the approaching object. Change the speed and color of the light. As a result, the occupant can easily recognize the change in the light emission mode, and can recognize the approach degree of the approaching object from the changed light emission mode.

  Further, in the present embodiment, the second light emitting portions 11 are provided on the pair of left and right door linings R, respectively. Then, of the pair of left and right second light emitting units 11, only the second light emitting unit 11 located on the same side as the opened door moves the light emitting portion 11a. As a result, the occupant can accurately grasp the approaching direction of the approaching object as well as the position of the approaching object (strictly, the left side or the right side of the vehicle V).
